Seasonic G-550 PSU enough for my system?

chromic · Oct 4, 2014

I5-4670k 4.5ghz @ 1.28v
r9 290 with mild OC ~1100/1300
Couple of fans
Antec h2o 1250
Corsair H70 (for gpu)
SSD & HDD

(it has 45A on 12v rail)

Yes it's enough.

650W would be ideal , but it's a great power supply and will cover it.

The PSU is extremely high quality, but the GPU with other hardware will really be pushing it to its limits, upgrade recommended. The system has 42A on 12V recommended but the demand is too high for safe and sound long term usage. Have you considered the 150W TDP and more powerful GTX 970?

chromic · Oct 4, 2014

no cash at the moment (bought the 290 for 230$)

Dark Lord of Tech · Oct 4, 2014

It's fine , it's high quality and can handle your specs.

MeteorsRaining · Oct 4, 2014

Fair enough, as said, even though it'd be pushing it, you should be fine for atleast sometime, but do upgrade the PSU as soon as you have the resources

Dark Lord of Tech · Oct 4, 2014

If you had a cheap power supply , I'd say no but you have a great one , you should be fine until you can upgrade.

+1, that's all I meant

chromic · Oct 4, 2014

290 max peak usage is like 250-300w and 4670k @ 4.8 is ~160w (so mine is probably liie 140w)

I dont think ill ever get those numbers in regular use.

(I mainly use my PC for gaming & occasional streaming)

Dark Lord of Tech · Oct 4, 2014

It's high quality , you will be fine , nice choice on the power supply.

chromic · Oct 4, 2014

Dont have it yet (at the moment chieftec a-80 750W) but the quality of that PSU is like "meh", so thats why i am "upgrading"

And also its 1.5 yrs old.

MeteorsRaining · Oct 4, 2014

If you don't have it yet, why not get a better wattage yet high quality PSU (not as high as G series, but still good), like XFX Pro 650W or EVGA 650G.

chromic · Oct 4, 2014

Id like to have a trusty/high quality PSU, rather than high wattage "low" quality psu

(you get my point)

MeteorsRaining · Oct 5, 2014

The quality of XFX Pro is high, higher than many others, look here:
http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html
G series is the same tier as Pro, but yes its a bit higher in quality, but XFX is NOT low quality, very reliable too.

I strongly recommend you to get a higherr wattage PSU than extremely high quality one. Don't worry about XFX's quality, its good enough. EVGA 650G is very high quality too.
PS: XFX is made by SeaSonic.

Ive narrowed my selection down to 2 PSU'S

seasonic m12II-620 ■ 620 bronze
seasonic G-550 ■ 550W Gold

Price difference is ~1$

MeteorsRaining · Oct 5, 2014

M12II 620W, the extra wattage is better. The quality is good too. May I know which website do you intend to get the PSU from?

chromic · Oct 5, 2014

http://www.jimms.fi/hae/g/1290/v/457/min/0/max/0/

I live in Finland so the prices are high.

MeteorsRaining · Oct 5, 2014

Your choice is fine, but for 90 bucks, this is extremely high quality, XFX (made by SeaSonic), 650W XXX:

chromic · Oct 5, 2014

hmm.. think ill still go with the g550,gold rating and it can withstand 110% power.

Thanks for assistance.

MeteorsRaining · Oct 5, 2014

I'm unable to grasp why you want to load the PSU to unsafe limits. Its ultimately your decision, I can only advise.

chromic · Oct 7, 2014

Forgot to update, went with XFX 750 XXX edition after some thinking.

MeteorsRaining · Oct 7, 2014

Great choice, will serve you real good
