Hiditec BZ V2 650W + AMD RX 9060 XT / RX 9070:
the €50 PSU that nails RDNA 4 — backed by independent test data
The RX 9060 XT (160 W) and RX 9070 (220 W) are AMD's most efficient RDNA 4 cards. Both pair perfectly with a 650 W PSU — and hardware analyst Router Eros has the numbers to prove the BZ V2 650W is up to the task.
At a glance
RX 9060 XT + mid-range CPU draws 280–330 W under gaming load. The BZ V2 650W runs that system at 43–51% rated capacity — right in its measured peak efficiency window of 86.25%.
RX 9070 + mid-range CPU draws 380–430 W. Still well inside the 650W envelope — the unit measured 85.76% efficiency at that load.
0.42% load regulation on the 12V rail. The voltage your GPU receives at peak load is virtually identical to idle — no sags, no micro-stutters from the PSU side.
ALPM compatible. RDNA 4 cycles aggressively between deep idle and full draw between frames. The BZ V2 650W is certified to handle those transitions without destabilising.
1. Real power draw: what full RDNA 4 builds actually consume
GPU TBP is only part of the picture. Here is full-system estimated draw for the most common RDNA 4 build scenarios, and where each one lands on the BZ V2 650W's measured efficiency curve.
| Build | Components | Gaming draw | PSU load | Verdict |
|---|---|---|---|---|
| 1080p (RX 9060 XT) | Ryzen 5 7600 + RX 9060 XT + 32 GB DDR5 | ~280–320 W | 43–49% | Ideal |
| 1440p (RX 9060 XT) | Ryzen 5 7600X + RX 9060 XT 16GB + 32 GB DDR5 | ~310–350 W | 48–54% | Ideal |
| 1440p (RX 9070) | Ryzen 7 7700X + RX 9070 + 32 GB DDR5 | ~380–430 W | 58–66% | Very good |
| 1440p (RX 9070 + X3D) | Ryzen 7 9800X3D + RX 9070 + 32 GB DDR5 | ~440–480 W | 68–74% | BZ V2 750W recommended |
2. The measured data: efficiency and 12V regulation from the independent review
Router Eros tested the BZ V2 650W from 10% to 115% load using a Passmark PM123 tester, multimeter and wattmeter. Below are the key rows — mapped to real RDNA 4 gaming scenarios.
| AC (W) | DC (W) | Efficiency | 12V | 5V | 3.3V | Gaming scenario |
|---|---|---|---|---|---|---|
| 325 | 280.3 | 86.25% ★ | 12.06V | 5.01V | 3.28V | RX 9060 XT — 1080p gaming |
| 390 | 335 | 86.10% | 12.04V | 5.02V | 3.28V | RX 9060 XT — demanding 1440p |
| 455 | 390.2 | 85.76% | 12.04V | 5.01V | 3.27V | RX 9070 — 1440p gaming |
| 520 | 442.6 | 85.12% | 12.04V | 5.01V | 3.28V | RX 9070 — stress scenario |
3. What is inside: key components identified in the teardown
Router Eros opened and photographed every major component. Here are the ones that matter most for long-term reliability and power quality.
Bulk capacitor
Toshin Kogyo TK LW — 400V, 330 µF, 105°C. Japanese manufacturer, top-tier thermal class. Directly supports the "Japanese capacitors" claim on the box.
+12V MOSFETs
3× Oriental Semi SFS130N06P — 60V, 130A. Synchronous rectification design: more efficient than traditional diodes and directly responsible for the tight 0.42% 12V regulation result.
Topology
APFC + Double-Forward (primary). DC-DC converters for 5V and 3.3V rails — a quality indicator that explains the excellent cross-load regulation across all minor rails.
Protection IC
Grenergy GR8329E — covers OCP, OVP, UVP, SCP and Power Good signal. Full active protection suite across all rails, confirmed in the independent test.
4. Router Eros's verdict: pros and cons
This is the independent reviewer's own assessment — not Hiditec's summary. His closing line: "Worth the price!"
Pros
- DC-DC topology on minor rails
- Excellent load regulation across all rails
- Long, individually sleeved cables
- ALPM compatible
- 105°C Japanese bulk capacitor
- Price — 49.99€
- 7-year warranty
Cons
- Samxon filtering capacitors on secondary side (105°C, functional — but not the top tier found in the BZ PRO line)
Which Hiditec PSU for your AMD RDNA 4 build?
BZ V2 650W — RX 9060 XT builds
Ryzen 5 + RX 9060 XT. Peak efficiency zone, verified regulation, ALPM certified. 49.99€.
