How much watt should I need for my chosen parts?

AVDPC · Dec 7, 2014

hello,

The parts that I will use:
Asus gtx 970 GPU
I5 4690k CPU
1tb Seagate HDD
and 4 fans (2 are red LED)

How much watts do I need?
600 - 650 -700 or 750?

Thanks!

550w will be plenty.

MAke sure it is from a quality company like Antec, XFX, Seasonic.

Is a corsair rm650 (80+, gold) okay?

tiny voices · Dec 7, 2014

Not the best quality unit.

I would prefer an XFX550 TS.

IF that Corsair is the ONLY option, then it would be ok I guess.

The PSU is the single most important part of a PC.

XFX PRO 550W Black Edition ATX ? , You sure it is enough? 550watts?

tiny voices · Dec 7, 2014

That will work great. Yes, the gtx970 uses very little power for how well it performs. 550w is plenty.

The GTX 970 will use about 150W, the rest o your system will use less than 100W, a bit more if you overclock a lot. A good 550W supply will handle that easily. This ould be a good supply
XFX TS 550W 80+ Bronze Certified ATX Power Supply

@Tiny Voices. I though that the lower end Corsair RMs, including the RM650 were Tier 2a.

Seasonic M12II-620 EVO, 620 Watt ? What do you think about this? (it's cheaper than the XFX, here in Belgium)

tiny voices :

The 550w and 650w RMs aren't too bad quality wise(but usually there are cheaper options that are just as good if not better). The the 750w, 850w and 1000w units that have quality issues.

DonkeyOatie :

Even since JonnyGuru himself started helping with the list it appears they are not as good as we have them listed at.

I always recommend skipping the whole RM line.

AVDPC :

That's a good PSU and will power the system just fine.

tiny voices :

The corsair RM psu aren't thath bad i think, i've read some good things about them on the internet.

tiny voices · Dec 7, 2014

Some of the RM units are actually pretty miserable in quality.

DonkeyOatie · Dec 7, 2014

The important thing is that the Seasonic the OP suggested is a great unit.

AVDPC · Dec 7, 2014

What happen if you chose a low quality PSU?

tiny voices · Dec 7, 2014

It could fail and fry the computer.

AVDPC · Dec 7, 2014

tiny voices :

Should the corsair rm650 freeze a computer with a gtx970?

tiny voices · Dec 7, 2014

Probably not but why risk it?

Just get a quality PSU.

AVDPC · Dec 7, 2014

The prices of the computer parts are very high here in Belgium. I try to build a gaming computer in a budget, it's very hard to find quality parts for low price.

tiny voices · Dec 8, 2014

That is correct, and some parts can be compromised a bit on, while others cannot be (PSU).

How much watt should I need for my chosen parts?
