Gigabyte GP-P750GM 750 W

Honest question: Why do manufacturers put two connectors on a single cable if they can't handle the spec of 150W per connector and 300W per cable?

I shudder when I see builds with high end cards on one cable.

Because there are lower power consumption cards with 2x PCIe. Each pin on the PSU side can handle 8-9A and it will have problems with anything above, either in a short period (if the load is too high) or in long term. 300W can be ok, with notable voltage drops and depending on cable length, but 350W and above will be a problem, especially if the voltage drops low.

exactly, before ampere it wasn't a problem at all, if the PSU is not a gutless impotent it will run without issues. only recently people begun discovering that vega and 5700xt actually need the power supplied that way to avoid crashing that plagued them. my gtx1080 was powered with a single cable on G2 650W for 4 years without a hitch, also didn't hear that it caused any problems on turing.

I have a 650 Watt Gigabyte PSU in my HTPC. It ran a Vega 64 and now a 5700 just fine I don't see a reason to upgrade. I have even used this with customer builds but they are all 2600, 3600 and below so a 650 Watt is overkill for a 65 Watt CPU. It does not hold a candle when it comes to quality compared to my HX1200i but for $75 CAD and a 5 year warranty (Especially how PSUs are just expensive). I guess the line I have must be new though because they are only now getting into the market. One thing I have learned though is if you are going to buy a modular PSU make sure it is from a brand that actually makes or has an excellent relationship with those that have been making High Quality PSUs for years like the HX series from Corsair.

I purchased a 750W one when it was on sale for $89 CAD. Put it into a customers build that has a 3500X and a 1660 Super.

I don't think it will stress it close enough to be a problem. But Gigabyte needs to get its act together.

Edit: Upon inspection, the PSU I ended up buying for a customer was the G750H model. Different PSU.

I wanted to replace my G750Н with this, because of the compact size and full modularity, but now I changed my mind.

I don't recall ever seeing that PSU before, Antec only lists their zen and classic neo-eco series but I found it on Newegg so it does exist.

I picked up the Antec NeoECO Series NE750G 750W to replace a PC Power & Cooling ModXStream Pro Series 500W 80+ Semi-Modular I've used for 10 years (bought it 12/2010 for $65)!

The only reason is that machines Zen 3700X, and now with an RX 5700X (that replaced an RX 590) is now perhaps pushing it a little too hard, although hasn't skipped a beat the last couple of days. Even so, I'll switch it over and sell the PC Power & Cooling ModXStream Pro for perhaps $25-30, not a bad return on investment.

I wish everyone in the hardware review industry did tests as brutal and extensive as those done in this article. The industry as a whole would be improved.

This shows what happens when a company loses focus, gigabyte got its hand dipped in too many sauces, and of course with having too many sku's over 70 sku's for a psu.

I think we bought the same one. It seems there was only one model available in Canada.

Actually, you can find the crappy one mentioned at memory express now. But previously, the G750H was available at memex before hand. Apparently those models are fine.

I also like how the poor model is more expensive than the one that isnt poor.

Got it I was looking at Canada Computers

Looks like Gamers Nexus is looking into this too, this is a spectacular failure on Gigabyte's part.
