ASUS ROG G20 Review: Tower Of Power

by John Nieves  August 19, 2015


We review the G20!

There’s an oft held belief in the PC gaming world that the more beastly your machine is, the bigger it should be. That’s generally not true of course – anybody can make a small, powerful PC, but it won’t be pretty or silent. ASUS’ G20 desktop manages to be small, compact and powerful, as well as have a design that makes it an instant winner in the eyes of gamers. Before we start, let’s take a look at the specs of the G20 as it came configured to us:

ASUS G20 specs:

  • Intel Core i7-4790 processor
  • 12GB of RAM
  • WiFi, Bluetooth, 4 x USB 3.0, 4 X USB 2.0
  • 6 Audio ports


One badass looking PC

To call the design of the G20 unique would be a big understatement – the G20 looks extremely badass, and the overall design is based off of Mayan architecture. The design isn’t just for looks as well – ASUS designed the G20 this way for better airflow and thermal management, even under full load. And while at first glance the G20 looks big, trust us when we say it’s a fraction of the size of most top of the line gaming-rigs, and a whole lot quieter.


The front of the G20 holds the Bluray drive near the top, as well as the two USB 2.0 ports and two audio jacks (one for actual audio and one for your mic). The power button in located on the front, near the Bluray drive. When the G20 is on, colored LED lights on both sides of the front of the G20 and the bottom of the chassis turn on. All the lights are completely customizable via ASUS Command, and can be changed to whatever color that you want.


Moving to the back you’ll see the multitude of ports, including the four USB 3.0 and two USB 2.0 slots, Ethernet port, 6 audio ports as well as the connectors for the power and the GPU. The G20 uses a very big power brick to supply all the power to it, which deletes the necessity of a power supply that most gaming rigs have.


Hardcore gamers who may be interested in the G20 can theoretically upgrade the innards, though because of the design of the thing, you’re limited to what you can change, at least in the version that was lent to us. Not that you’d want to anyway – opening the shell of the G20 instantly voids your warranty. But that usually doesn’t stop most tinkerers, so if you’re hell bent in changing the innards, you can, but again, you’re limited to what you can change: you can stuff up to a GTX 750 in there, or really any video card that’s the same size as long as it doesn’t require a separate power supply. People who want the G20 but want a beefier GPU can get video cards up to the GTX 980, though you will have contend with a separate power adapter for the GPU along with the power supply for the G20. ASUS also told us that the RAM is not user replaceable unfortunately and while you can stuff more storage in the G20, you’re relegated to 2.5-inch drives as opposed to regular 3.5-inchers. We’re also a little baffled why the G20 doesn’t come with SSD storage as standard – considering the amount of money you’re paying for it, you’d think they’d throw that in as a freebie.

Performance that’s enough for most games in the market

While the G20 doesn’t sport top-of-the-line GPU, the hardware configuration that it has is more than enough to run most modern PC games on high. We used it with a few games – Devil May Cry, Project CARS, ARMA 3 and Red Orchestra 2 on full HD resolution with the graphics turned to high. For Project CARS, the game ran at an acceptable 30 FPS, with a dip or two in the high 20’s. In Devil May Cry, the G20 managed to achieve 40 to 50 frames, though recording with FRAPS usually dropped that to just 30. With ARMA 3, we managed to get the game running on 30 FPS though running it on high was a bit too much even for the G20 (ARMA 3 is one of the most resource-heavy games you can find because of the wide terrain). In Red Orchestra 2, we managed to get the G20 running on 60 FPS, but dropped down to 40 when running fraps and recording.

The best thing about the G20 is that it’s dead quiet. Even running on full load, we really didn’t hear the fans of the G20 working. We were actually stumped the first few seconds when we initially setup the G20 because we couldn’t hear the fans working – only when our monitor showed the ASUS logo did we breath a sigh of relief that we did things right.


Just like other pre-built PCs, the G20 has a myriad of additional software built-in for a better gaming experience. Game First III allows you to prioritize gaming traffic to help prevent lag spikes while you’re playing. AEGIS gives you an overview of what’s happening with your PC in a very cool way.

ASUS Command gives gamers a way to personalize and change the settings of the G20 depending on their tastes.


Verdict: A compact gaming powerhouse that even hardcore gamers will enjoy

At the end of the day the ASUS G20 isn’t the fastest or the best gaming rig out there. And before anybody says it yes, you can probably build a gaming rig that has better specs than the G20. But then again, that’s not the reason why you’ll buy it anyway. In terms of gaming cred, the G20 is legit, and can play most, if not all, games out in the market without any major issues. It’s probably one of the coolest desktop rigs we’ve seen, and quite possibly the quietest one we’ve tested so far.


While its Php 63,995 sticker price is not for the faint-hearted, gamers who pony up the dough for ASUS’ gaming rig will be more than happy about the money that they’ve spent. As an added bonus, ASUS is also throwing in a limited edition ROG jacket as well as a Logitech G502 gaming mouse with every purchase.

    Equals = 56,430. Siguro sa tirang 7,565 pwede nang pang monitor kaso 18 inches lang or 21 ewan. Kung may tira edi keyboard at mouse combo.

    Sa specs na yan halos lahat ng laro pwede mo nang laruin kaso doblehin mo nalang yung Memory card.

    Pero sasabihin ko lang ah mas may iba pang tindahan na mas mura sa PCX.
    Ginamit ko lang yung PCX kasi sila ata yung pinakakilala sa PC parts.

    there’s a reason why ganyan ang size nyan. parang nasa gitna ng laptop and desktop na yan. one thing is for sure, you are not part of the target market ng G20 😛

    I’d still go with a gaming laptop sa ganyang price though, just plug and play.

    wala ka pang OS bobo. kung bumili ka ng original na OS konti lang difference. nagmarunong ka kulang ka naman sa utak. obvious na pirated OS lang ginagamit mo.

    Kuya makabobo ka naman. Sorry kung hindi ko nalagay yung OS. Yung mga OS ngayon nasa 3K-7K yung range so dagdagan mo nalang yung presyo niyan. Tsaka bakit naman ako gagamit ng pirated kung yung ginastos ko is aabot ng 60K? Tsaka parang ewan naman kung gagamit ka ng pirated sa PC mo baka magkaroon pa ng anomaly sa system.

    O cge buuin mo yang 56k mong yan tapos punta ka asus iharap mo sa mga engineer,technician,designer yan specs mo ireklamo mo yung specs nila.

    Hays! Tandaan mo milyon nagastos nila bao ilabas yan sa market kasi hindi naman iisang utak ng tao bago nagawa yang rog g2 na yan.
    At malamang katakot takot na burn in test ginawa nila dyan bago i release sa market yan kasi may pangalan silang inaalagaan.

    At isa pa hindi lang ikaw nakakaalam na nyan, kahit asus at kami alam yan. Kaya nga may 3 years na warranty to insure the quality diba.

    Sir wag naman pong magalit ang sinasabi ko lang is kung bibili ka rin lang naman ng Desktop bakit hindi pa sa mas praktikal na way tsaka hindi naman me nagrereklamo sa specs. Siguro nga po target to para sa mga hindi gaanong marunong mag build ng PC or para doon sa mga taong gusto lang na maliit na space para sa Desktop. Sana maunawaan niyo. Sorry kung naoffend ko po kayo.

    Di naman ako nagagalit. Yes dun na ako sa praktikal na mas mataas na specs pero mahirap pa rin tapatan ang 3 years na warranty nila lalo kamamahal ng pyesa nyan sa loob. Nagbigay sila ng 3 years kasi quality ginawa nila at yun ang kinamahal nya. Masasabi mo rin ba di rin praktikal yun?

    Actually buying parts by parts will give you a lot of lifetime warranties. But of course you would only build yourself a gig if you’re a tinker or a technician, otherwise you’d buy this ASUS

    I love Unbox PH. I check it multiple times in a week, but I need to rant because some reviews lately are more like product placements.

    I do not know how the reviewer can give this a passing grade and recommend it to people. First of all, the part selection is terrible. Putting in an i7 and 12gb of RAM and then a crappy GTX 745 is just plain stupid. The i7, compared to the same generation i5, does not yield a big difference when playing games, at most 3-10 FPS. RAM is overkill, 8gb is enough. I understand that this PC is trying to look high end to the average consumer since they spec it like a high end phone, great processor, big RAM but then pairing it with a GTX 745? Really? And you want how much for this again? Its just plain stupid.

    Secondly, the games tested are dated and its getting 30 FPS and then you say “A compact gaming powerhouse that even hardcore gamers will enjoy”. I laughed a little when I read that. The recommendation sucks. If you said “Hardcore gamers! Go build your PC. Do not be stupid and try adding a 980 and another power supply since that cost 40k+ already, making this a very expensive crappy PC” then I’d probably not be writing this right now.

    However, if this product is marketed towards MOBA players (LoL, Dota, HoN), the crappy video card is sufficient for mid-high settings at 60fps. Or for those that want to have a very slim and compact PC, then I understand.

    BTW, in case you didn’t know or you just forgot to mention, or maybe I’m right and this is actually a product placement rather than a review, its silent because the graphics card doesn’t have a lot of power.

    My advice to buyers checking this out. If you really want it, most probably because of the case, go buy it.

    But if you want a slim and compact gaming PC and thinking this is amazing because the reviewer said that even “hardcore gamers” would be happy, look elsewhere. Ask around in various FB groups or forums for specs. Bring it to a PC shop like Dynaquest or PC Hub and they will build it for you. As for the case, Lian-Li, Fractal Design and Silverstone offers cases of similar form.

    Hi Popoyista! Thanks for the comment. We’ll do a review of the content that we’ve put out but I’d like to assure you that the only thing we have for sale on this site are banner ads.

    I rather build my own gaming rig that is more badass looking (specs/aesthetics) than this with exactly the same price or cheaper.

    Pretty meh specs. Priced too high for a device with a 2 generation old GTX745. The only thing it has going for it is the nice looking case.
