Is the vs650 ok?

xMaGnu5MaXx · Sep 19, 2016

Hey, ive built my pc about a year ago, here are the specs

A68HM Grenade mobo
amd a10 7870k
corsair h60 water cooler
vs 650
gtx750ti
2x4 hyperx ram
1tb seagate hd

Now im planning to upgrade several things

mobo to a crossblade ranger (bit of a sucker for looks)
gc to a rx480 8gb (and please i dont want to hear "the 1060 is better, i have my reasons")
and an ssd

but im wondering if the vs650 is good enough and wont fail me, i really dont want to spend more but if i have to then id go for a evga 650w g2 , and suggestions?

Cooler Master VS? Or Corsair VS?

I assume Corsair, as it's more common. It's ok, and nothing more.

Nobody can guarantee a PSU won't fail you - even the 'best' PSUs out there, and the VS series is far from the best.
The EVGA G2 650W is a quality PSU and would be a welcome upgrade, but even a quality 500W would be sufficient.

For price + quality, the Rosewill Capstone G650 can be had for $65 / $55 after rebate:

The XFX TS 550W is $63 outright:

If you prefer to stick with the VS:

A rough guess would be no more than 350W from that setup with the RX480 - although that's likely over-estimating.
I would expect the A10 will bottleneck the RX 480, never allowing it's full 'power', and keeping power draw to a minimum.

Therefor, the VS650 *should* be more than capable on wattage alone - but it's impossible to say for sure that you won't have issues.

thanks, for the detailed info, but do you think the 7870k will be a bottleneck? (It's over clocked to 4.7ghz btw)

Yes, it will be. The A10 is an "APU", who's intent it to be a good balance of CPU & GPU performance. There's some limited CPU performance as it's also trying to be a GPU - and you're not using the GPU, so there's some 'wasted' raw processing power (in a very simple sense)

AMD haven't done a complete revamp of their architecture in a long time - that's why Zen is so eagerly awaited.
As a result the A10, despite not launching until mid 2015, is based on architecture a few years old - it's not particularly efficient or powerful.

Older A10's were clearly bottlenecking R9 280's & 290's, with the RX480 performing up to 30% greater in certain benchmarks, so those bottlenecks will still be there, and worse in some cases.

For GPU intensive tasks with minimal CPU impact, you'll see improvements, absolutely.
Anything particularly CPU intensive though, and you GPU upgrade won't be as noticeable.

Now that you mention the OC, that changes the 'keeping power draw to a minimum' comment I made. Overclocking your CPU can change/increase power draw quite dramatically depending on voltages. The VS (again, assuming Corsair) is not really appropriate for that type of setup.

Yes to clarify it is corsair, and I'll probably upgrade the the evga 650w g2, but now I have another problem.... How bad would this bottleneck be? (Also thanks for all the replies, it really helps.)

The G2 650W is a quality PSU, so if you're upgrading - that's definitely a great call.

As for how bad the bottleneck will be....... I can't say for sure. I can't find any benchmarks with that pairing to reference for you (as, honestly, the pairing is not the best use of funds pairing an APU with a discreet GPU).

I would speculate the bottleneck would be pretty noticeable in CPU intensive tasks, but that's just an educated guess. I can't quantify what that would be.

As a quick frame of reference, here's Far Cry 3 with various CPUs & a GTX 980 at 1080p.

It's not up to date at all, and looking at older generations - and DX11, but it'll give you an idea.

Your A10 is probably in the FX-4100 range (maybe a little less tbh), with your GPU being a little below the GTX 980.......

As you'll see, there's around a 30FPS difference between a comparable CPU (the FX-4100) and the 'ideal' gaming CPU - in that chart, see the i5-3470 or i5-3570K (comparable CPU's today would be the i5-6500 or i5-6600K), so the CPU will definitely hold you back significantly in some tasks/games.
