Psu question

[Beavus]

Hi all

I have a Psu 700w and it has 2 PCI-e 6+2 connectors but the second connector splits from the first 1 so i'm not sure if i can use it for a gpu with 8 + 4 connector.

I assume i can but i want to make sure before i plug in a 3070 so if anyone knows for sure thx in advance.

Yes, using a single daisy-chain cable with a graphics card is generally fine. If the power supply you're using isn't chinesium garbage, the power cable melting isn't a concern. What specific model PSU are you using?

• PSU ATX 700W Thermaltake TR2 S (80 PLUS / Haswell Rady)

TR2 S is a bad group regulated PSU. You don't want to power a RTX 3070 with it.

That's a pretty old design. "haswell ready" is the biggest indicator, haswell CPUs were relevant about a decade ago. Older units have been known to struggle with newer demanding graphics cards, the RTX 30 series in particular has very demanding power spikes on the higher end cards.

 

Are you shopping in the United States? There are some very affordable PSUs to recommend

No in Europe but i'm surprised tho because some sources say 220 w peak power use for a 3070.

If i add everything up i have total +-600W peak power.

I'll just use my used psu and see what happens..... It's working now with an old 1080ti (300w) so.

Thx anyway

Cuz the 30 series has power spikes

Group regulated so it has a very bad voltage regulation with recent hardware.

Double forward so it can't handle powerspikes without coilwine and banging transformer.

Very low quality.

Bad or even missing protections.

Which of the 50 countries?

Unfortunately it's not just the size of the power spike, but how fast it happens. The transient response is important, unfortunately that's not something you can find on a spec sheet

 

Most of corsair's options are affordable and good. CXM, CXF, TXM and such. Avoid the VS though, a bit too cheap.

AH k thx for the info...... 

I got some time..... still waiting for the release of those 4060 4050? so maybe prices for the 30 series drop some more......

Guess it's better not to risk my new mb and new gpu and buy a new psu.

OK, get this https://tweakers.net/pricewatch/1849562/nzxt-c650-gold-v2.html or the 750/850w. For ATX3.0 you can look at the Pure Power 12 M.

yes a 750 seems better so i have some room for other stuff and only 10 euros more. 

Guess it will be a be quiet since they are really quiet according to some reviews.
