Question PSU recommendation for my new gaming build ?

[Brandon Umali]

Hi, I'm from the Philippines.

Here's the build I'm about to purchase, I just need your recommendation on which PSU should I proceed with.

MOBO: MSI MPG B650 CARBON WIFI ATX AM5 or GIGABYTE B650 AUROS ELITE AX
GPU: Sapphire NITRO+ Radeon RX 7900 XTX 24 GB
RAM: G.SKILL Trident Z5 32GB 2 x 16GB DDR5 6000Mhz CL30 or TEAMGROUP T-Force Delta RGB 32GB 2x16GB 6000Mhz CL30 DDR5
SSD: 2pcs Western Digital Black SN850X NVMe 2TB PCIe Gen 4 SSD - 2TB
CASE: Deepcool CH560 DIGITAL ATX Mid Tower Case or Montech Air 913 Max
CASE FAN: 3pcs Cooler Master MOBIUS 120P ARGB 75.2 CFM 120 mm Fan
MONITOR: 2pcs Gigabyte M27Q-X 27.0" 2560 x 1440 240 Hz

Available 1000W PSUs to choose from :
1. MSI A1000G PCIE5 1000 W 80+ Gold Certified Fully Modular ATX
2. Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX 1000 Watt
3. Seasonic SSR-1000FX (White) Focus GX-1000 - 1000W 80 Plus Gold - White
4. BE Quite Pure Power 12M 1000watts 80+ Gold Fully Modular PCIe 5.0

You can choose any model from the list above. They are good, ATX 3.0 certified (the HX1000i is not ATX 3.0 spec but it passes the requirements anyway) units.

I would try for the Trident Z Neo ram kit if its available. They are tuned for AM5.

 

[Darkbreeze]

Yeah, couple of things there.

As Lucky mentioned, you don't want a Trident Z5 kit. Those are intended for Intel configurations. You want to use the G.Skill memory configurator to make sure any kit you get will be compatible specifically with the motherboard model you've chosen before deciding on a kit. Even kits made specifically for AMD platforms might not play nice on certain boards so it's always best to check there even if it's an AMD kit like the Trident Z5 Neos and Flare X5, but some of the Ripjaws and non-NEOS Trident kits will work too, you just need to check the configurator to make sure. Personally I'd stick to the kits intended for AMD that have EXPO profiles rather than just XMP profiles. Some of their Ripjaws kits have both XMP and EXPO profiles, and will work fine if they are listed as compatible on G.Skills compatibility utility, and are often just as good or better than some of the Trident kits depending on the model of the kit.

I'd also make an effort to look for motherboards with the B650E chipset rather than the older B650 chipset as there are quite a few benefits to the newer chipset including 24 PCIe 5.0 lanes instead of only 4, generally speaking more VRM power phases, a x16 PCIe 5.0 slot and two PCIe 5.0 M.2 slots versus only a single PCIe 5.0 M.2 and no PCIe 5.0 x16 slot on the older chipset, and support for a couple more USB ports than B650. Of course, if the price difference in the region you are buying is too significant then it may not be something that's a deal breaker for you going with the older chipset, but I'd at least look around first.

As to the PSU, sorry Lucky, but you've made a mistake there. The A1000G is not ATX 3.0 compatible from what I can see and seems to have issues with poor efficiency under low loads, not particularly quiet, loose 3v and 5v load regulation, high inrush current, minor issues with hold up time and power ok signal, and not the greatest transient response for a unit of this caliber. Seems like there are better options unless you are finding a terrific deal on it, and then I'd still have to think very hard about it.

The Seasonic unit is "ok", but clearly not one of their best. The Pure power 12m units are also not the greatest thing out there but not the worst either. Of those units, the HX1000i would definitely be my first choice. But you might also be able to find something like one of the Thermaltake GF3 units that has better caps selection than the Pure power 12m. I definitely agree with Aris that Teapo caps on a unit of this type is a pretty poor decision by Be Quiet. There are also some other issues with the PP 12m such as APFC tuning (Especially for those with 230v power grids), high OCP tuning and questionable 12v load regulation.

I'm not saying none of the other units are viable, but if the price difference isn't enormous, I'd opt for the HXi unit myself, followed by the Seasonic or like I said, there are others options out there that might be better if available like the Thermaltake GF3 models.

@Darkbreeze You might be think about the old A1000G MSI unit. The unit listed by the OP above is the new revised PCIE5 version. the 850W is reviewed by Aris and it was ATX 3.0 compliant. Using the same platform, the 1000W is also ATX 3.0 compliant.

And i agree with Darkbreeze's rating of the listed models.

 

[Darkbreeze]

I was not aware there was a new revision. Thanks for correcting me.

Seems both the 850w and 1000w new models do still have some issues though especially in the area of poorly tuned protections on both capacities. I would not expect to see that on a high end unit like this.

A few other things as well, at least as outlined by Aris on the 850w model.

• 12V-2×6 marked socket on the modular board actually 12VHPWR
• Noisy operation
• I would like to see a higher-quality fan used
• Highly set OCP triggering point at 3.3V
• Low PF readings
• High inrush current at 230V
• Below 70% efficiency at 2% load
• Not efficient 5VSB rail
• The 3.3V rail failed in one of the transient response tests (not ATX v3.0 ones)

None of these are things you want to see on a unit that costs $170.00 in my opinion. But if the price is right and it's the better of only a handful of options, then it's maybe viable. Problems with OCP triggering on newer graphics cards because the protections aren't set properly could be a problem though. Setting OCP and OPP too high to avoid issues from power excursions seems like a bad way to solve the issue. It would be a lot better to tune those correctly and simply recommend users to get units which are actually the proper capacity for the configuration, including some built in headroom to ensure that triggering from lack of sufficient capacity isn't going to happen.

At 1000w though with even a decent model, those hopefully shouldn't be factors with a 7900 xtx anyhow. Still, if I pay that much for a PSU, I want to not even have that worry at all. Just my opinion.

Hi guys, thank you for your inputs. I just found a new PSU seller and decided to go with thier product which is:

FSP Hydro Ti Pro 1000W 80+ Titanium ATX 3.0 (PCIe5.) Modular PSU (HTI-1000M GEN5)

I think this is better than the previous 4 earlier, kindly correct me if I am wrong.

Well, that thing probably isn't cheap, but yes, it's supposedly a pretty terrific unit.
